यदि \(b\neq6\), तो ((b-6)x^{15}+9x-6-2) की डिग्री क्या होगी?
If \(b\neq6\), what will be the degree of ((b-6)x^{15}+9x-6-2)?
Explanation opens after your attempt
A. (15)
Concept
When \(b\neq6\), the coefficient of \(x^{15}\) is not zero. Therefore the highest power remains (15).
Why this answer is correct
The correct answer is A. (15). When \(b\neq6\), the coefficient of \(x^{15}\) is not zero. Therefore the highest power remains (15).
Exam Tip
\(b\neq6\) होने पर \(x^{15}\) का गुणांक शून्य नहीं है। इसलिए सबसे बड़ी घात (15) रहेगी।
